The virtual flight test can simulate the 3-DOF flight of aircraft in the wind tunnel, and realize the integration of aerodynamics/flight/control of aircraft. Based on the similarity criteria, a scaled virtual flight aircraft model is designed, and the flight control system of wind tunnel virtual flight test is established. The 1/9 scaled model and 1/15 scaled model virtual flight test are realized in the wind tunnel. It is proved that the results of virtual flight test can be applied to the prediction of aerodynamic characteristics and control response characteristics of full-scale aircraft through the test.
